6.8.2Before Running FLASH The windows in FLASH UPDATE contain all the instructions
UPDATE | you need to update the instrument. However, there are a few | |
| things to consider before running the program. | |
| • | Updating your instrument erases the data stored |
|
| in its memory. This includes all readings and most of |
|
| the program settings. FLASH UPDATE replaces most |
|
| program settings with factory settings. Before running |
|
| the program, collect the data and record your program |
|
| settings. Then, after updating the software, reprogram |
|
| the instrument. |
| • | If you have Flowlink, Teledyne Isco strongly |
|
| recommends using it to update 4200 Series Flow |
|
| Meters. Flowlink lets you collect the data stored in the |
|
| instrument before updating the software. It also leaves |
|
| the program settings in the instrument unchanged, |
|
| eliminating the need to reprogram them. Then Flowlink |
|
| updates the software, it uses the update files on the |
|
| FLASH UPDATE disk and disregards the FLASH |
|
| UPDATE program. Refer to the Flowlink Help files for |
|
| more information. Use FLASH UPDATE only if you do |
|
| not have Flowlink available. |
• The instructions in the following section, Running FLASH UPDATE, assume you are running the program from the update disk. However, you may prefer to copy the disk’s contents to your hard disk. Before copying the disk, create a new directory for the FLASH UPDATE program and the update files. The program and the update files must be in the same directory. Furthermore, that directory must be the current directory when you run the program.
• If you receive several update disks over time, copy the update files and the program when copying the contents of a disk. This ensures that you have a current version of FLASH UPDATE as well as the new update files. Depending on your selection in the preferences window, you may see the window in the margin (left) listing all files in the directory. This window appears only when the directory or disk contains more than one version of the update files and the Preferences option for Show Update File is “All Update Files.” (See About Prefer- ences.)
